# This script converts binary files (u-boot.bin) into so called
# bootstrap records that are accepted by Motorola's MC9328MX1/L
# (a.k.a. DragaonBall i.MX) in "Bootstrap Mode"
# 
# The code for the SynchFlash programming routines is taken from
# Bootloader\Bin\SyncFlash\programBoot_b.txt contained in
# Motorolas LINUX_BSP_0_3_8.tar.gz 
# 
# The script could easily extended for AMD flash routines.

# From the posting to the U-Boot-Users mailing list, 23 Jun 2004:
# ===============================================================
# I just hacked a simple script that converts u-boot.bin into a text file 
# containg processor init code, SynchFlash programming code and U-Boot data in 
# form of so called b-records.
# 
# This can be used to programm U-Boot into (Synch)Flash using the Bootstrap 
# Mode of the MC9328MX1/L

# Press any key to start programming ...

# Programming ...
# Verifying flash ... succeed.
# 
# Programming finished.
# 
# So no need for a BDI2000 anymore... ;-)
# 
# This is working on my MX1ADS eval board. Hope this could be useful for 
# someone.
